Apple and Microsoft are now worth more than $4 trillion each.
This is the first time that Apple’s market capitalization has surpassed the $4 trillion mark, making it the third company to surpass this milestone after Nvidia and Microsoft. Redmond first crossed the mark in July, but its valuation has since fallen slightly to $3.9 trillion, before returning to $4 trillion on Tuesday following news that it had signed a new deal with OpenAI.
Apple’s growth has been impressive, reaching $1 trillion in 2018, $2 trillion in 2020, and $3 trillion in 2022. After the launch of the iPhone 17 series, Apple’s stock price has skyrocketed and appears to be outperforming its previous versions. The company is scheduled to announce its fourth quarter 2025 results on Thursday, October 30th.
Microsoft is also growing thanks to demand for OpenAI’s large-scale language models and Azure cloud services that provide the computing power needed to train AI models. The company announced Tuesday that its roughly 27% stake in OpenAI is worth about $135 billion. The tech giant will report its quarterly results on Wednesday.
Google’s parent company Alphabet is also approaching the $4 trillion milestone, with a current market capitalization of $3.25 trillion.
